Odd. It works here:
4.1-RC, UP1000, 600MHz 21264A
linux_base-6.1
linux_devtools-6.1.
ccc-6.2.9.002-2
cpml-5.0.0
libots-2.2.7
<10:09am>thunder/gallatin:tmp>cat hello.c
#include <stdio.h>
main()
{
printf("hello world \n");
}
<10:09am>thunder/gallatin:tmp>make CC=/compat/linux/usr/bin/ccc hello
/compat/linux/usr/bin/ccc -O -pipe hello.c -o hello
<10:09am>thunder/gallatin:tmp>./hello
hello world
<10:09am>thunder/gallatin:tmp>ldd hello
hello:
libc.so.6.1 => /lib/libc.so.6.1 (0x0000000040004000)
libots.so => /usr/lib/libots.so (0x0000000040238000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000000160100000)
Its probably an installation issue. I just beat on the symlinks until
it worked ;)
Did you run the
/compat/linux/usr/lib/compaq/ccc-6.2.9.002-2/alpha-linux/bin/create-comp-config.sh
script? If I install the rpm with -vvv, I noticed this script was
generating error messages. I ran it manually, using
/compat/linux/bin/sh. I'm not sure if this helped or not..

Cool! I'm glad to hear it.

I'll have to defer to somebody else for testing the fortran compiler.
I disavow any knowledge of fortran ;-)

You're welcome. I"m glad I could help!
